  1. A linear function has a slope of −2 and passes through (0, 6). What is its equation?

    Answer: y = −2x + 6

    Using y = mx + b with m = −2 and b = 6 gives y = −2x + 6.

  2. Solve the inequality: 2x + 1 < 9

    Answer: x < 4

    2x < 9 − 1 = 8, so x < 4.

  3. Which statement describes the domain of a function?

    Answer: All possible input values

    The domain is the set of all permissible input values (x-values) for which the function is defined.

  4. Evaluate: −3(2x − 4) when x = 1

    Answer: 6

    Substitute: −3(2(1) − 4) = −3(2 − 4) = −3(−2) = 6.

  5. What is the solution to the system: x + y = 10 and x − y = 4?

    Answer: x = 7, y = 3

    Adding the equations: 2x = 14, so x = 7; substituting: 7 + y = 10, y = 3.

  6. Which of the following is equivalent to 3(x − 2) + 4x?

    Answer: 7x − 6

    Distribute: 3x − 6 + 4x = 7x − 6.
